C_[ACTION]_expl#
This pattern performs collective access from all processes to a common file, with an explicit file pointer.
This benchmark is based on the following MPI routines:
MPI_File_read_at_all/MPI_File_write_at_all
for the blocking modeMPI_File_.._at_all_begin/MPI_File_.._at_all_end
for the nonblocking mode
All other parameters and the measuring method are the same as for the
P_[ACTION]_expl
benchmark.
